From outside the vehicle:
1.
Remove

the passenger-side engine cover (see page 183)
2.
When the two-minute timer completes, remo

ve the
dispstick (orange loop), wipe it clean, and reinsert it (flat
side of loop toward oil fill cap)
3.
Remove

the dipstick and check the oil level. It should be
between the upper and lower marks. Add oil if needed.
When finished, select a different display in the driver
information interface.

n Recommended Engine Oil
Use full synthetic, 0W-40 motor oil such as
Ultimate
Full Synthetic Motor Oil, Type 3, 0W-40, available at your
authorized Acura NSX dealer.
Ambient Temperature
Acura cannot ensure proper engine operation and durability if other engine oil is used..
NOTICE n
Adding Oil
Unscrew and remo

ve the engine oil fill cap.
Add oil slowly.
Reinstall the engine oil fill cap and tighten it securely.
Recheck the engine oil level (see page 185).
Oil Fill CapFlat Side
Do not fill the engine oil above the upper mark. Overfilling the engine oil can result in leaks
and engine damage.
NOTICE
Use only oil that displays an API Certification Seal on the
container. This seal indicates the oil is energy conserving
and that it meets the American Petroleum Institute’s latest
requirements.

n Resetting the Engine Oil Life
If you change or
replace the vehicle’s engine oil yourself, you must reset the engine oil
life. Use the right selector wheel on the steering wheel to make selections in the driver
information interface.
Whee lRight Selector
Set the power mode to ON. Roll the wheel until the oil life displays in the driver information
interface.
Press the wheel for at least 10 seconds, until you enter reset mode.
Select All Items Due, then press the wheel. The maintenance items disappear, and the
engine oil life display returns to 100%.
Failure to reset the engine oil life after a maintenance service results in the system showing
incorrect maintenance intervals, which can lead to serious mechanical problems.
NOTICE
Engine Coolant
Park the vehicle on level ground. Check the reserve tank and the coolant level in the radiator.
We specify Acura Long Life Antifreeze/Coolant Type 2.
n
Checking the Coolant Lev

el
Open the hatch and remove the driver’s side engine cover (see
page 183).
If the coolant level in the reserve tank is below the MIN mark,
add the specified coolant until it reaches the MAX mark.
Inspect the cooling system for leaks.
Reserve Tank MAXMIN
If temperatures consistently below −22°F (−30°C) are expected, the coolant mixture should
be changed to a higher concentration. Consult your authorized Acura NSX dealer for more
information.

n Adding Coolant
Make sure
the engine and radiator are cool.
Turn the reserve tank cap counterclockwise and relieve any
pressure in the coolant system. Do not push the cap down
when turning.
Push down and turn the cap counterclockwise to remove it.
Pour coolant into the reserve tank until it reaches the MAX
mark. Put the cap back on the reserve tank and tighten.
Reserve Tank
Cap
Removing the reserve tank cap while the engine is hot can cause the coolant to
spray out, seriously scalding you.
Always let the engine and radiator cool down before removing the reserve tank
cap.
WARNING
Pour the fluid slowly and carefully so you do not spill any. Clean up any spills immediately;
they can damage components in the engine compartment.
NOTICE
Inverter Coolant
Check the inverter coolant level every time you refuel
n
Checking the Inverter

Coolant Level
Open the hood.
If the inverter coolant is below the MIN level, have your
vehicle serviced at an authorized Acura NSX dealer.

Testing of Readiness Codes
Your vehicle has readiness codes as part of the onboard self-diagnostic system. Some states use these
codes for testing to verify your vehicle’s emissions components are working properly. The codes may
not be read if you go through the testing just after the battery has gone dead or been disconnected.
To check if they are set, turn the vehicle on without starting the engine. The malfunction indicator
lamp will come on for several seconds. If it goes off, the readiness codes are set. If it blinks five times,
the readiness codes are not set.
If you are required to have your vehicle tested before the readiness codes are set, prepare the vehicle
for retesting by doing the following:
1.
Fill the gas tank to appro

ximately 3/4 full.
2.
Park the v

ehicle and leave the power system off for 6 hours or more.
3.
Make sure the ambient

temperature is between 40°F and 95°F (4°C and 35°C).
4.
Turn the power system on without

touching the accerator pedal, and let it idle for 20 seconds.
5.
Still in Park (P), increase the engine speed

to 2.000 rpm and hold it for about three minutes.
6.
Let the engine idle for 20 seconds without

touching the accelerator.
7.
Select a nearby, lightly

traveled major highway where you can maintain a speed of 50 mph (80
km/h) for at least 20 minutes. Drive on the highway with the vehicle in D and in SPORT mode. Do
not use cruise control.
8.
Drive in city or suburban traffic

for at least 10 minutes. When traffic conditions allow, let the
vehicle coast for several seconds without using the accelerator pedal or the brake pedal.
9.
Park the v

ehicle and leave the power system off for 40 minutes.
The readiness codes are erased when the battery is disconnected, and set again only after several
days of driving under a variety of conditions.
If a testing facility determines that the readiness codes are not set, you may be requested to return at
a later date to complete the test, or see your authorized Acura NSX dealer.
Long-Term Storage
If you need to park your vehicle for an extended period (more than one month), there are
several things you should do to prepare it for storage. This helps reduce possible deterioration of
vehicle components and overall condition, which allows you to get the vehicle back on the road
with minimal delay. These are:
•
If possible, store your NSX in a garage

or enclosed area.
•
Fill the fuel tank completely

.
•
Change the engine oil and filter

.
•
Wash and dry the exterior completel

y.
•
Clean the interior. Make sur

e the carpeting, floor mats, etc., are completely dry.
•
Put the transmission in (P). Release

the parking brake.
•
Leave one window

open slightly (if the vehicle is being stored indoors).
•
Connect the 12-volt battery

to an accessory battery charger. For more information on how
to maintain your 12-volt battery, consult an authorized Acura NSX dealer.
•
If the vehicle is

to be stored for a longer period of time, it should be supported on jack
stands to raise the tires off the ground to prevent tire flat spotting. Consult an authorized
Acura NSX dealer for information about the correct jack stands.
•
Support the front wiper

blade arms with a folded towel or rag so they do not touch the
windshield.
•
Cover

the vehicle with a breathable cover, one made from a porous material such as cotton.
Nonporous materials (such as plastic sheeting) may trap moisture, which can damage the
paint.

208 || 209
SPECIFICATIONSMAINTENANCE
• If possible, remove the vehicle from the garage or enclosed area, remove covering, and
periodically run the engine until it reaches full operating temperature (the cooling fan cycles
on and off twice). Preferably, do this once a month.
•
To maintain the High V

oltage battery, drive your vehicle for more than 30 minutes at least
once every three months.
If road conditions are not suitable or desirable for driving, the following alternate procedure can
be used to maintain the vehicle’s High Voltage battery if local laws permit idling:
1.
Remove

the vehicle from the garage or enclosed area to prevent carbon monoxide
accumulation.
2.
Depress the brake pedal and pr

ess the ENGINE START/STOP button as you normally would
to start the vehicle.
3.
Allow the vehicle

to run for 30 minutes. Time spent at idle stop still counts as part of this
30-minute run.
Paint Care
Your vehicle’s paint requires up to 60 days from the production date to fully cure. During this
time, avoid applying any wax or paint sealant-type products, as they could hinder the curing
process and affect the paint’s durability.
You may polish the paint during these 60 days if the polishes do not contain any wax or paint
sealant ingredients. Use only clean, high-quality microfiber towels or pads, as they are softer
material and have less chance of scratching the finish. It is absolutely necessary to keep the
microfiber towels or pads properly cleaned and maintained before using on your vehicle.
